Lakefield, Australia - Australian police on Wednesday said they may have located a man who had been missing for days after human remains were found inside a crocodile euthanized as part of the search.

The 65-year-old local man went mysteriously missing on Saturday while fishing with a friend in the Kennedy River at Rinyirru (Lakefield) National Park in the north-eastern state of Queensland.

He was identified as Kevin Darmody by local media reports.

During the search operation, police captured two crocodiles, 13 feet and 9 feet in length, believed to be involved in the man's disappearance upstream from where he was last seen.
